Not with gas units. They have a spark igniter - just like your gas
grill. Gas works when the power is out!

Ain't the spark powered by 120 VAC?


I'm the last person to ask that question. I am told that striking a
match will light the pilot on a gas unit.

"The Bosch engineers have proven that water can indeed make fire. The
pilot is ignited by a super-concentrated spark generated by a
micro-turbine. The micro-turbine is activated by a request for hot
water in the house."

I never knew about turbines, but tankless systems have gotten better
over the years.

Imagine that. Power is out and the gas unit fires up!


To bad the pump in the well didn't start with the water
heater...LOL....What good is a heater with no water ??? LOL...I suppose
those with city water could use it but how often and how long is the power
out in the city ???
